RE: [AMaViS-user] Amavis child hanging

[SRH-Lists <gi...@33...>]

I think I have this one figured out.  I started amavis like this:
amavisd debug-sa > /home/filter/amadgb 2>&1 &

and waited and waited for it to crash (watched pot/no boiling), finally,
I decided it was fine and went to deploy it at a much higher volume
site, et voila, back to the occasional run away amavis process.  Ran
amavisd as above, and this time it had the decency to hang while I was
watching.  Here is what happened:

Apr 14 21:59:20 filter.example.com amavisd[28790]: (28790-04) CALLING
NoMailAudit::check
Cannot open bayes databases /var/spool/spamassassin/bayes_* R/O: tie
failed: Too many open files
razor2 check skipped: Too many open files IO::Socket::INET: Bad protocol
'udp' at /usr/local/lib/perl5/site_perl/5.8.3/Mail/SpamAssassin/Dns.p
m line 409, <GEN6> line 702.

Ah ha!!

A quick google for those errors led me to this:

The jist of which is that OpenBSD has a pretty low setting for max
openfiles unless you:
1)  Increase it for the default login group in login.conf  -OR-
2)  add the user that amavis is using to the daemon login group (which
has higher settings)

This seems (from some random searching) to be happening to a few more
folks, although it always gets described differently.

I suggest a FAQ item for this.
